SAFETY-CATCH FOB JEWELRY.

Specification of Letters Patent.

Application filed February 13, 1909. Serial No. 477,802.

To all whom it ma/y concern:

Be it known that I, ANDREW O. BURGESS, a subject of the King of Sweden, residing at Newark, in the .county of Essex and State of New Jersey, have invented certain new and useful Improvements in Safety-Catches for Jewelry; and I do hereby declare-the following to bea full, clear, and exact description of the in ention, such as will enable others skilled in the 'art to which it appertains to make and use the same, reference being had to the accompanyin drawings, and to figures of reference marked thereon,

which form a part of this specification.

hook and is adapted to be rotated, whereby an opening in the ring is brought in register with the opening in the hook to permit the passage of the pin, or it is swung around so as to close this opening in the hook, whereby hook and in the ring are out of register. The inner ring is operated manually to be locked and unlocked, and the ring can be swung inward, to a slight extent, so'that one end can be. formed into a catch to enga e the hook'so that the ring can be locked in its position when it is closing the hook. a The invention is illustrated in the accompanying drawin ,in which- Figure l is a si e view showing a pin and a catch of my improvedconstruct on. Fig. 2 is a detail 3 is a similar view with the catch closed. Fig. 4 is a vertical section through Fig. 3. Fig. 5 is a view similar to Fig. 3, but of a slightly modified form of constructioi'i.

I inay apply this device to any form'of jewelry employing a in to fasten it, and I illustrate a body portion 10 havinga standard 11 in which is pivoted thepin 12 so that it can be swung, after it is inserted in a garment, so that t can pass under the hook to prevent the accidental Withd rawal of the pin. The hook to receive the pin comprises a stem 13 which is bent into a hook 14, the

metal b ing preferably flattened and made a ated'of course in size,

of the catch in its open little wider so as to give a larger surface, although this particular configuration is not absolutely necessary. The hook is slotted as zit-15 and is'pr'ovided on its inner facewith a. groove 16. A rin 17* is placed in the the ring havingan openin which is adapted to be placed in and out o register with the opening in the hook, according: to the way the'ri'ng is swung, a stud 18 which. rojects out through the slot 15 and provi es means for its manual mani nlation. The stud 18 can be placed anyw ere in the ring, but-'is preferably placed near one end, whichis the end oppo- "site to the one "which closes'and opens the 'openinginthebook, The other end of the stem is provided with a'nose 19 which is adapted tocotiperate' withthe hook when they areswung so as t oclose theopening'in the hook-and lock the ringinits closed'position.

positions of'the' hook 19 and the edge 20 with which it enga es to lock'the ring in its closed position.

tracting the ring .so' as'to allowit to' slide I overthe edges 20. The views are exagger and the hook in reality has but a slight edge so that a manual push on the stud 18'will' dislodgethe nose l9 and. permitthe openin "of the hook, but enough of a projection is ormedto prevent the accislipping around of the ringwhich would occur, possibly, if'there' were no means for locking the rink'shut. l

In Fig. 5 is illustrated a modified form of construction in which the nose 21 is formed in one end of the ring, andwthe end of the hook is formed into a cotiperating latch 22 so that the ring is locked 1n its 0 osed osition, due to thespring action both o the hook and the ring. p

' If desired, the slot- 15 can be made of a length calculating to liinit the movement of the ring in each direction as in Fig. 5.

The particular form and design of hook and ring are not essential, and I esire to be understood as not limiting myself to the particular formation and proportion of the parts described and illustrated herein.

' Having thus described my invenhen, what "I claim is z 1. A safety catch comprising. hook havhe 11050 19 has'a "slight spring action due to thepossibility of .conv groove and is adapte to be rotated therein,

The ring i's'operated by 1 'In Figs. 2 are"illustratedthe two dental opening-of the hook by the gradual ing a slot therein and having a groove on its inner face, a ring rotatablyarranged in the groove and having an o ening to be placed in or out of register Wit the opening in the hook as the ring is rotated, and a stud on the ring projecting through the slot in the hook and providing for the manual manipulation of the ring.

2. A safety catch comprising a hook, the hook having a groove on its inner face, a ring rotatably. arranged in the groove, the ring having an o ening adapted to be laced in and out 0 re ister with the openmg in the hook, the ring having a spring action whereby it can be contracted, a nose on one end of the ring adapted to engage an edge of the hook by its spring action, and means for manually manipulating the ring.

3. A safety catch comprising a hook having a. slottherein and having a. groove on its inner face, a i'im adapted to fit the groove and be rotata ly arranged therein with its inner face flush with the inner face of the hook, a'stud on the ring projecting through the slot in the hook, the ring having an opening to be placed in or out of register with the opening in the hook as the ring is manipulated by the stud, and a nose on the end of the rin adapted to engage the hook -to form a late for locking the ring in its closed position.

In testimony, that I claim the foregoing,

I have hereunto set my hand this 11th day of February, 1909.
